Briefly, this error occurs when Elasticsearch’s machine learning feature, autodetect, is prematurely terminated, causing some results not to be processed. This could be due to insufficient resources, a crash, or a manual stop command. To resolve this, ensure that your system has enough resources to handle the load. Check for any signs of crashes in the logs and rectify any identified issues. If the process was manually stopped, avoid doing so during a critical operation. Lastly, consider increasing the timeout settings if the termination is due to a long-running process.

} else if (process.isProcessAliveAfterWaiting() == false) {
// Don't log the stack trace to not shadow the root cause.
logger.warn("[{}] some results not processed due to the termination of autodetect"; jobId);
} else {
// We should only get here if the iterator throws in which
// case parsing the autodetect output has failed.
logger.error(() -> "[" + jobId + "] error parsing autodetect output"; e);
